Description
The Defense Advanced Research Projects Agency (DARPA) is seeking information on the design of international payment systems with a focus on privacy, efficiency, and security. The goal is to create a payment system that is both private and performant, allowing for secure and efficient transactions while protecting user privacy. The agency is interested in understanding the tradeoffs between financial privacy, transaction volume, and payment security, as well as the technical challenges and potential solutions for achieving provably private and performant payment systems. Some of the key areas of interest include:
• Defining privacy for a payment system and understanding the limits of current practices
• Identifying fundamental tradeoffs between financial privacy, transaction volume, and payment security
• Developing an appropriate privacy threat model and understanding the differences between security and privacy in payment systems
• Exploring technical innovations and solutions for achieving private and performant payment systems
